这是我写的一个pl sql代码。用动态光标写。
有两个表,s_dept和s_customer。
他们有一个相同的项region_id。
现在我想打印s_customer表里的name项,条件是s_dept表中的name叫peter。
这是错误报告。
cursor c_kk is

------解决方案--------------------------------------------------------
游标的名字和下面的行变量名字是重复的,你用什么语言都不可能写出来个
String a = "abc";
int a = 0;
------解决方案--------------------------------------------------------
第8行c_kk改成ckk就行了。
